BACKGROUND OF THE INVENTION

1. Discussion of the Related Art

Most wheelchairs provide for removeable attachment of footrests. The footrests are pivotally and removeably fitted on the front legs of the wheelchair with the use of foot rest brackets. The foot rest brackets are permanently attached to the front legs of the wheelchair above the front wheels. These foot rest brackets cause numerous injuries ranging from bruises and skin tears to severe lacerations that can take weeks to heal. Such injuries occur primarily during wheelchair transfer of ill elderly patients with limited mobility. Injuries happen whether the patient is being assisted or getting into the chair on their own. While foot rest brackets on wheelchairs are inherently dangerous, and continue cause severe injuries, there is no solution available in the prior art for protectively covering these foot rest brackets.

The present invention provides a convenient, highly effective and inexpensive device for protectively covering the foot rest brackets on the wheelchair in order to prevent injuries to persons using a wheelchair. More particularly, the injury protective device of the present invention easily attaches by wrapping the device around the front leg of the wheelchair in covering relation to the foot rest brackets. The device includes a multi-layer, sandwiched construction of polyester batting and densified batting forming a thick cushioned barrier over the foot rest brackets and around the front legs of the wheelchair.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the several views of the drawings, the protective cover device of the present invention is shown and is generally indicated as 10. The protective cover device 10 is specifically designed for easy attachment on the front legs 22 of a wheelchair 20 in a manner that completely covers the projecting foot rest brackets 24 on the front legs. The protective cover device 10 includes a main body 30 which, in a preferred embodiment, has a rectangular configuration. In one preferred embodiment, the dimensions of the main body are 11 inches wide by 9 inches tall with an approximate thickness of 1.5 to 2 inches.

The main body 30 includes on outer case 40 formed of a soft, durable fabric material and including a top side 42 within an exterior face 43 and a bottom side 44 with an exterior face 45. The top and bottom sides of the outer case 40 are joined (e.g., by stitching) about their peripheries to form an interior pocket 48. The interior pocket is filled with a batting filler 50 of sandwiched construction. More particularly, the inner batting filler 50 includes a core filler 52 formed of a premium densified batting that is sandwiched between upper 54 and lower layers 56 of a 100% polyester batting. In a preferred embodiment, the core densified batting is approximately 1 inch thick, while the upper and lower polyester batting layers are each approximately ¼″ thick.

A plurality of tacking stitches 60 are made in a spaced arrangement, as seen in FIGS. 1 and 2. Each tacking stitch 60 extends from the top side 42 of the case 40 to the bottom side 44 of the case, pulling the top and bottom sides of the case closer together, and thereby creating a tufting effect. The spaced arrangement of tacking stitches serve to create bend points to increase flexibility of the main body 30, so that the main body of the device can be easily wrapped around and contoured to the configuration of the wheelchair leg 22 and the protruding foot rest brackets 24. The plurality of tacking stitches also serve to increase the stability of the core batting material fillers. More specifically, the plurality of tacking stitches 60 help to prevent shifting of the interior batting material 50, particularly when hand or machine washing and drying.

The main body 30 of the protective cover device is secured and held in place around the front leg 22 of the wheelchair 20 with the use of straps 70 and hook and loop fasteners. More particularly, the device includes a pair of straps 70 that are each secured at one end to a side edge of the main body 30. The straps 70 extend from the side of the main body and are adapted to be secured to the top exterior surface 43 of the outer case 40 when the main body 30 of the device 10 is wrapped around the front leg 22 of the wheelchair 20. More specifically, the bottom sides 72 of the straps 70 are provided with a hook component 74 of a hook and loop fastener for mating, releaseable attachment with corresponding loop components 76 on the top side exterior face 43 of the case 40. An I.D. label 80 is sewn to an opposite side edge of the case 40 and provides identification and care instructions.

The protective cover device 10 of the present invention is constructed using zig-zag stitching for added strength and increased visual appeal. The thread used is durable cotton quilting thread. The construction process according to the preferred embodiment is as follows:

-   -   1. Attach loop part of hook and loop fastener (face up) to         20″×12″ outer material by stitching the perimeter and stitching         diagonally from corner to corner.     -   2. Mark locations of tacking points     -   3. Fold outer material in half, thus dividing the 20″ side in         half and creating a 10″×12″ piece of folded material.     -   4. Place material with the folded edge down and with the loop         material of the hook and loop fastener facing upward and to the         left.     -   5. Begin stitching the left side while adding the I.D. Label         between the pieces of fabric. The label should now be folded in         half to create a 2″×¾″ loop.     -   6. Stitch the right side while adding two securing straps (with         the hook component of the hook and loop fasteners facing down)         between the pieces of fabric, thus creating a three sided         pocket.     -   7. Into the pocket, insert the densified batting, sandwiched by         the two pieces of 100% polyester batting.     -   8. Stitch the top edge to complete the enclosure of the filler         products.     -   9. Perform the tacking stitches in the designated locations to         create tufting effect and increase the stability of the fillers         during cleaning maintenance (i.e., hand or machine wash and         drying).

The protective cover device is easily attached by wrapping the main body around the front leg of the wheelchair, and over the foot rest brackets. The plurality of tacking stitch points serve to increase flexibility and thus provide bend points that contour easily around the wheelchair leg and foot rest brackets. To complete the installation, the securing straps are attached to the outer facing top side of the case using the hook and loop fasteners. It is important to face the hook and loop fasteners and the securing straps away from the patient's legs to avoid discomfort and possible injury to the skin.

While the present invention has been shown and described in accordance with a preferred and practical embodiment thereof, it is recognized that departures from the instant disclosure are fully contemplated within the spirit and scope of the present invention.
